App1ication filed December 16, 1912, Serial 110. 237,061. Renewed March8, 1916. Serial No. 82,920.

To all whom it may concern Be it known that we, JOSEPH MERRITT andWILLIAM A. SAwYEmcitizens of the United States, residing at Hartford'andWest Hartf0rd,-respectively, in the county of Hartford and State ofConnecticut, have invented a new and use'ful lmprovement in Machines forMakingWire Links, of which the following is specification! y Thisinvention relates to a machine which is designed to make-both closedlinks or rings and open links orstaples'fromcontinuous lengths of wire,and to load' these closed and open links, or rings and sta ples,

into magazines in such 'conditionthat the filled magazines containing"many thousand links can be transferred to amachine which will take therings'a'nd staples and assemble them into a"continuous link-mesh fabric.v 11' The object of this invention is to provide a machine which'willvery rapidly and accurately produce large quantities'of closed or openlinks from continuous lengths of wire and load the links into magazinesin proper condition for the subsequent manipulation alluded to.

The machine which is illustrated as embodying the invention at eachrevolution feeds a plural number of wires the proper distance to providethe correct lengths for thelinks. The lengths of wire fed are then cutoil and by suitable benders formed into U-shape. The ends of theUeshaped pieces are then coated with a fiuxing material so thatsubsequently they may be securely united. If closed links are to beproduced the U-shaped pieces with fluxed ends are then by formers bentso as to bring the ends together, but if open links are to be'produeedthe ends are bent toward each other only slightly.- After this the linksthus onto the magazine rods,

ing closed links, or rings. F 2 shows an elevation looking at theleft-hand side of the machine shown in Fig. 1. Fig. 3 shows 7 an;elevation looking at the front of the ma- Chlllfl.

r0112, which is an idle roll, is mounted on a slide 4 which is thrustback by a spring 5 so that therewill be the necessary pressure betweenthe two rolls to give-the required frictionfor, feeding the wires. .Thetension of the spring 5 is adjusted by a nut 6 on abushing that isscrewed into the. bracket 7' that is fastened to the frame. ,A nut 8 isprovided to draw the slide forward and openthe space between the feedrolls. (Fig. 11) The r0113 is fixed to an arbor 9 which bears a ratchetwheel 10 and a lock wheel" 11. Loose onthe arbor 9 between the ratchetwheel and the lock wheel is a plate'12, and

mounted on this plate is a pawl 13 that engages theteeth of the ratchetwheel. Connected with the plate is a link 14and jointed lto the'link isa swinging arm 15. At the joint between the link and arm is a roll 16that by a spring 17, connected between the frame and the link, is heldin contact with the periphery of the cam 18. (Fig. 10).

i,ise,

Adapted to engage with the locking-wheel is a bolt 19. This bolt isnormally thrust forward by a spring 20 and is drawn back by the lever 21which bears a roll 22 that is held in contact withthe periphery of thecam 23. (Fig. 10). The cam 18 through "the link 14, pawl 13 and ratchetwheel 10 intermittently imparts a rotatory movement-to the feed wheel 8for feeding the wires. The cam 23, through the lever 21 draws back thelocking bolt from engage m'ent with the teeth of the lock wheel topermit this movement of the feed wheel, but

after the movement has been completed, the

bolt is thrust forward by its spring and engages the locking wheel so asto hold it with the feed wheel turned the right amount for feeding thecorrect length of wires to form the links. The cams 18 and 23 are fixedto a shaft 24. (Fig. 10). e Fastened to the lower end of the shaft 24 isa bevel gear 25 (Fig. 4),,which is engaged shaft 32 is'a spurv gear, 33that is engaged by a spur pinion 34. This pinion is by a clutch 35connected with the driving shaft 36 which bears the driving pulley 37,when i; r

the clutch cone 38 is moved up to the clutch by the arm 39 on the rod 40that is adapted to be moved bythe hand lever 41. By means. of this handlever the clutch is engaged or released for driving the whole machine.(Fig. 1).

The feed rolls advance the wire through a guide block 42 past a mandrelpin 43 until the ends strike a gage plate 44. (Fig. 9). If closedlinksor rings areto be formed the mandrel pin is circular in cross section,as shown in Fig. 28; if open links or staples are to be formed themandrel pin is oblong in cross section, as shown in Fig. 27. With theinner ends of the fed wires 45 in the position shown in Fig. 28, thebender 46 is moved forward. This bender carries a plate 47 which firstengages the wires and holds them against the pin. As the bender movesforward, the cutter 48 is forced back so as to out off the wires. (Fig.29). The continued forward movement of the bender bends the ends of thesevered lengths of wires around the mandrel pin the end of the benderbeing shaped so as to accomplish this, as shown in Fig. 30. The benderholding the wires bent about the pin continues its forward movementuntil the ends of the wires are brought into contact with the face ofthe fluxing wheel 49. This wheel which At theor stopping i has a slowintermittent movement coats the ends of the wires with such material aswill 7 cause them to be securely united when they are subsequentlysoldered or brazed. (Fig. 31). The bender with the wires is thenretracted and two formers are brought together so as to bend the ends ofthe wires toward each other. (Fig. 32). At this time the bender and pinwith the wires are moved slightly forward so as to cause the ends of thewires to come together and form the ring. (Fig. 33). If open links orstaples are to be made, the formers only turn the ends of the wires in aslight amount, as shown in Fig. 27. a

The cutter 48 is a spring plate that is fastened to the guide block 42.(Fig. 9). The cutter is forced back for severing the wire by theengagement with its front edge of the inclined wall 51 on one of theformers 50 when that formeris moved toward the other former. (Figs. 27,29).

The holding plate 47, which is carried in a recess in the bender slideis thrust forward by a spring 52. This spring is stiff enough to causethe plate to hold the wires against the mandrel pin so that they willnot get out of place when out, and will be bent evenly about the pin,and yet will let the plate yield when the bender moves forward forbending the wires. (Figs. 4, 34). The bender slide 46 at its rear endcarries a roll 53 which is engaged by the periphery ofthe cam 54that iscut so as to give the bender the movements stated. (Fig. 9). The cam 54'is keyed to the vertical shaft 24. (Fig. 4).

The formers 50 are mounted on the front ends of levers 55 and 56. (Fig.9). These levers are yoke-shaped and at their rear ends are fastened tostuds 57, as shown in Figs. 35 and 36. An extension 58 of the upper partof the lever 55 carries a roll 59 that runs in contact with the cam 60which is near the upper end of the shaft 24. An extension 61 of thelower part of the lever 56 bears a roll 62 that runs in contact with thecam 63 which is on the shaft 24 in a lower plane. (Figs. 4, 9, 35, 36).The levers are normally held with the formers separated and with therolls against the cams by a spring 64. (Fig. 9). These cams are cut sothat as previously described, the lever 55 is first moved to cause thecutter 48 to sever the wires and then after the wires are bent andfluxed to move the levers 55 and 56 so that the formers close togetherand complete the shaping of the link.

The mandrel pin 43 is fastened to a block 65 that is secured to a slide66 which is movably located below the bender slide 46. (Figs. 4, 34).The pin slide 66 is normally held back by a spring 67 that thrustsbetween the rear end of the slide and a stud 68 that is fastened to thebender slide 46.

Attached to the bed back of this slide 66 is a bracket69 thathas a screw70 which butts against the rear end of the slide. The spring 67 normallyholds the slide 66 back so that the mandrel pin 63 stands just in frontof thebender. ever, is so adjusted that it prevents the pin from beingretracted so far as to obstruct ,of this slide and projecting beneaththe lower end of the ejector is a block 74. Springs connect this slideand the ejec- The screw 70, howtor. These springs normally hold theejector.down, but they are sufficiently flexible to allow the ejector tomove forward with the pin slide by which it is carried when the ends ofthe bent wires are taken into contact with the flux wheel. (Figs. 4, 5,37). The ejector slide is lifted by one end of the bell crank lever 76.The other end of this lever carries a roll 77 which is held in contactwith a cam 78 on the shaft 79 by means of the spring 80. (Figs. 5, 6).The shaft 79 extends from front to rear and at its back end has a bevelgear 81 that meshes with a bevel gear 28. (Fig. 6). By means of thismechanism, when the feeding, bend- :ing, and forming mechanisms arebeing operated, at the proper time determined by' the cam78, the ejectoris lifted sodas to raise the links from theposition in which they areformed (Fig. 13), onto the lower end of a magazine rod 82. (Fig. 14).

The fluxing wheel 49 is supported on a shaft 83 and its lower edge turnsin a pan 84, which contains the fluxing compound. (Fig. 4). This pan isremovably supportedby the bed of the machine below the fluxing wheel.(Fig. 3).. The fluxing wheel shaft 83 on its front end has a ratchetwheel 85, engaging with which is a pawl 86 that is mounted on a plate 87which is loosely supported on a sleeve that surrounds the shaft 83.(Fig.4). A link 88 connects the pawl plate-87 with one end of a bellcrank lever 89. The other end of this lever has a roll 90 which is heldin contact with the periphery of the cam 91 on the shaft 79. (Fig.3). Bymeans of this mechanism the fluxing wheel is given a slow intermittentrotatory movement. In order-to regulate the amount of fiuXing materialon the edge of the wheel so that just the right amount, will be appliedto the ends of the fishes, a gagefwheel92' is provided. This gage Wheel:is mounted on a shaft 93 which has a'wormwheel 94ethat meshes with afw'orm 95" on a shaft .96. front enact the shaft 96has a gear 97 thatmesh s'witli agear 98 which is driven by a-pinion 99, on the frontend-of the shaft (Fig. The

plate 122 has parallel vertical grooves 123 I in which lie the rods 82.The plate 122'at each end has a tongue 12 1 which fits a vertical groovein the edge of the support 125. The support 125 is fastened to the topof the magazine supporting slide 126. (Figs. 1, 8, 8). When the clamps118 are loosened the staple magazine is free to be lifted out. The ringmagazine is simply dropped into place so that it can be readily removed.Either one of these magazines can be used with this machine, dependingupon whether open links or closed links are to be made.

In a machine already built, and which is illustrated by the accompanyingdrawings 10 fine wires. are fed in at each movement of the feedmechanism. The ends of these 10 wires are simultaneously severed, andareall bent, fluxed,forn1ed and carried up together Onto a magazine rod.Each rod holds in this particular machine 350 links, that is, each rodis filled by 35 revolutions of the 'machine. After a. rod is filled, thewire feeding, cutting, bending, fluxing, forming and'ejecting mechanismsare stopped and simultaneously mechanism for feeding the magazine sonsto move another rod over the mandrel pin is set into operation. Afterthe'magazine has been moved, the mechanism for accomplishing this restsand the other mechanisms resume their functions.

When the magazine is moved the rods that have been filled with links arecarried with their lower ends over a rail 21a (Figs. 1,

2, 3 4), which keeps the links from dropping olf. The magazine slide126, upon which the magazine supports are fastened, is dove-tailed andlies in a dove-tailed guideway in the top of the frame. (Figs. 1, 2, 4).Adjustably fastened to the top'of the magazine slideis a feed plate 127with ratchet teeth in its front edge, and above this is a slide bar 130is connected by a link 131 with the upper end of a lever 132, the lowerend of which is connected by a link 133 with a crank stud 1 16 that isadjustable on the end of the shaft 13 1. (Figs. 22, 23). When this crankis rotated the lever and links and pawls feed the magazine and move anempty rod into position to receive links. Adapted to engage with theteeth of the lock plate 128 are two bolts 135 one of which is set half atooth in advance of the other so that first -one engages a locking.tooth and then the other. This permits the lockingteeth to be a roll 139that is held in contact with the cam 140 on the shaft 134, by a spring141. (Fig.

22) The cam 140 through the lever 138 at the proper time withdraws thelock pins from the teeth of thelock plate and thus releases the magazineslide and allows it to be fed. After the magazine has been fed, one orthe other of the locking bolts enters a tooth and holds it in position.The spring 141 not only tends to hold the lever 138 with the roll 139against the cam 140 but causes one of the locking bolts to enter a notchin the locking plate, the yoke plate swinging according to conditions.In order to release the magazine feed by hand when desired, a cam 142 ispivoted on the end of the lever 138. This cam engages the edge of theframe and it is provided with a handle 143 which can be swung out sothat the cam will force the end of the lever 138 forward and with drawboth of the locking bolts from the teeth of the lock plate. The cam 142is connected by a link 147 with one'end'of a lever 144, the other end ofwhich is connected with a sliding bar 145 that carries pins 148 adjacentto the feed pawls. When the locking bolts are thrown out by the movementof the cam handle, these connections move the pins 148 against the pawlarms so that the driving points of the pawls are held out of engagementwith the teeth on the front edge of the feed plate. (Fig. 22). When thefeed pawls and the locking bolts .are thus disengaged, the magazineslide and the magazine which it carries are free to be slipped sidewiseout of the machine.

The shaft 134 which carries the cam that actuates the magazine lock andthe crank which actuates the magazine feed, extends rearwardly and issupported by suitable bearings on the top of the frame. Fastened to-therear end ofthis shaft is a disk 149 (Fig. 1). This disk has one ratchetnotch engaging which, so as to hold the magazine mechanisms, is a pawl150 that is on the end of a stationary arbor 151 which has an arm 152that is drawn down by a spring 153. The disk carries an arbor 154. Thisarbor back of the disk has a latch 155, and in front of the disk has anarm 156. A spring 157 pulls this arm and latchtoward the axis of thedisk. (Fig. 18).

Extending in line with the shaft 134 but disconnected therefrom is ashaft 158. (Fig. 1). On the end of this shaft 158 adjacent to thedisk149 that is fastened to the shaft 134 is a single toothed drivingwheel 159. At the proper time the latch 1 carried by .th! disk 149 isreleased drawn into position to be engaged by the tooth ofthe drivingwheel 159 so that the disk 149 and shaft 134 which operates the magazinefeed and lock will be actuated by the wheel 1 59 and shaft 158. (Figs.18, 19). The shaft 158 on the rear end has a gear 160. (Fig. 1). Thisgear meshes with a pinion 161 that is designed to be'connected with ashaft'162 by means of a clutch 163.

(Figs. 2, 6). The shaft 162 on its inner end has 'a bevel gear 164 thatmeshes with a bevel gear 165 on-the shaft 32. (Fig. 6). The shaft 32, aspreviously described, is geared to and driven from the driving shaft 36when the clutch on that shaft is engaged. The clutch 163 is adapted tobe moved for clutching and releasing the pinion 161 by the fork 166,which has its lower end connected with a rod 167 that extends through 1the'base tothe front of the machine and is adapted to bemoved in onedirection by a spring 213 andin the other direct-ion by a hand lever168. (Fig. 6). By pulling this lever the magazine feeding and lockingmechanisms are connected with the driving mechanism. The spring causesthe disconnection of these mechanisms.

On the shaft158in front of the gear 160 is a'pinion 169 that meshes witha gear 170 fastened 'to a pinion 171 that meshes with a gear 172. (Figs.1, 2). The gear 172 is fastened to'a shaft 173 on the rear end of which.is a cam 174 and on the front end of which is a cam 175. (Fig. 1). Heldby a (spring. 176 in engagement with the periphery of the cam 175 is aroller 177 on a rocker arm 178. This rocker arm is fixed to one end ofan arbor '179. On the other end of this arbor is a latch operating lever180. (Figs' 1, 18). The free end of the lever 180 has a lug 181 thatprojects toward the front, and the free end of the latch 155 has a lug182 that projects toward the back.

(Figs. 18, 19, 20, 21). With the lever 180 in its normal position on thelow part of the cam 175, the lug 181 on the lever engages the lug 182 onthe latch and holds the latter back so that the driving wheel 159rotates without turning the disk 149. hen the high part of the cam 17 5oscillates the lever 180, the lug 181 on the lever is lifted above thelug182 on the latch so as to release the latter and allow it to bedraw'n'by the spring 157 into the path of the'tooth of the wheel 159.Vhen the parts are engaged in this manner the disk 149 is driven by thedriving wheel 159 for actuating the magazine mechanism. Thespring '17 6immediately returns the lever 180 so that as the disk 149 makes onerevolution is drawn, out froinits engagement with the p tooth of thedriving wheel 159. This disconnects the parts so that the disk. 149stops.

(Figs. 1, 2). This rocker armfis fastened tothe rear end-of anarbor 185' which on its front end hasa rocker arm-186that extends down into the bed. The lower end of this arm.

186 is connected with a slidingbar 187,

(Figs. 6, 12),;ana thelower end of the arm 186 andfthe' bar 187 aredrawnin one direc- {tion by a spring 188.. (Fig. 12). Secured to this bar isadoub1e cone 189 which is free to slide'on a rod'190; Secured to thisrod isfa fork 191,:which is arranged to throw the clutch 31.; -('Fig.,6).. Between one end offthe' cone and a collar 192 fixed to the rod is,a'spring 193, andbetween the other end ofithe cone and a collar191 fixedto the rod isa spring (Fig, 12). Pivoted to the frame near one end ofthe double cone is a lever 196 having a screw 197 that is adapted to,engage one end ofthe double cone and a tooth 198 that is adapted toengage the collar 192. Aspring 199 tends-to, draw up. the

lever 196. Pivoted to the frame. near the other end ofthe double cone,is a lever 200 which has ascrew .201- adapted to engage the end of thecone and a tooth 202 adapted to engagethecollan194., (Fig. 12). Thislever is held up by. a spring'203. As the arm 186 is moved 1110118,direction by means of the cam 17 4, the double cone is moved so as tocompress the spring195 until the cone ment. ,,-(Fig. 12).

and the bar 187 moves the cone 189 so as to compress thespring 193 untilthe screw 197 is engaged by the cone'and the tooth 198 is disengagedfrom the collar 192 and allows the rod 190 to be thrown in the oppositedirection. (Fig. 12). As the rod is thrown in this direction, the clutchis moved so that the clutch lug 30 engages the clutch lug 29 andconnects the shaft 32 with the shaft 27 and sets in operation the linkmaking mechanisms. The cams are so timed and the clutches thrown so thatthe shaft 32 is disengaged from the shaft 27 when the 'magazinefeedmechanisms are to be actuated, and the shaft 32 is connected with theshaft 27 when the magazine feeding mechanisms are stationary and it istime to feed, cut, bend, flux, form and eject the wires. When the shaft.32 is connected with the shaft 27 by the clutch for this purpose,

. the cam and the lever are holding the latch so that the shaft 158 andthe shaft 1341 are disconnected and the magazine is stationary. (Fig.18). 1 p I 7 After the lastmagazine rod has been filled with links themachine is stopped. To accomplish this automatically a block 205 isadjustably clamped to one end of the magae I zine slide 126 (Fig. 1), sothat during the feedof the magazine after the last rod has 7 been filledthe block 205 will engage and depress the rod 206 which is normally heldraised by a spring 207. (Figs. 25, 26). The lower end of the rod 206 isconnected to one end of alever 208. The other end of the lever has ashoulder 209 that is adapted to engage a lug 210 that projects from asleeve (Figs. 25, 26). The r0d167, as previously described, extends tothe rear of the machine and carries the spring 213 and fork 166 whichthrow the clutch 163. A lever 212 is also engaged with the rod 206. Whenthe magazine reaches the predetermined limit of its feed and the block205 automatically depresses the rod 206, or when that rod is depressedby means of the hand level-212, the catch lever 208 is oscillatedandreleases the rod 167 which is thenmoved by the spring 213 so .as towithdraw the clutch 163 and disconnect the shaft 162 from its drivingpinion 161. (Fig. 6 This causes the stopping of the whole machine, forat the time "the magazine is being fed, the link making mechanisms aredisconnected and stationary.
